Internal Flash not working-Canon Eos 40D

I took pictures at a birthday party with an external flash. No problems. Then we went to a girl scout event and I took pictures with the internal flash. No problems. I come home and want to take a picture and on auto, or any automatic flash setting, the flash is not coming up. I hit the fash pop up button: nothing happens. There is no code, and it isn't saying the flash is blocked. It is just shooting at a very slow speed to compensate for the low light because the flash isn't coming up. There was no trama to the camera to cause this. Thank you for your help. I feel very upset that it isn't working and I can't figure why. Ruth

Try defaulting the menu to settings to factory defaults? This may clear the external flash information from the cameras memory?

I've had this happen to me too and I've been researching about it. Aparantly it happens because the camera still think the external flash is attached. If you go into the menu and under flash control, try ot enter the settings for built in flash. If this is the problem it will tell you here that the external flash is still attached. From what I have read to far, I'm not sure how to fix it. I would reccomend taking it in somehwere. I dont htink its a hard problem to fix.

Showing Error 5 all the time. Can't take pictures


This will take longer to write then to do it. Error 5 in my experience can be memory card, internal flash or actually an unlocked lens. The lens unlock button is pretty big and sometimes gets pushed in as my clients are zooming or twisting the barrel somehow. What I've had to do is shut the camera off, remove the battery. Unlock the lens ( I wait a second or two) then lock it back in place. Another problem was having an external flash installed and hit the internal flash button. The number 1 problem I've found was the Memory card, either it was (is) a new card that hasn't been formatted to the camera, a memory card that was formatted in the computer (that really messes with their brain) and another thing was continually using the delete button on the camera, or if it's a new card and you have formatted it and formatted it again and it still doesn't work try another card.
Okay the last suggestion and what actually happened to me on my Canon EOS 1D Mark II and III I was using 4gig cards bought 8 gig cards and went nuts cause they wouldn't work. Went on Canon's site and downloaded the updates which ended the problem.

I have a Canon EOS 40D camera. We are having problems with using an external flash. The pictures always come out extremely dark with the external flash. The flash seems to work fine, it flashes...


I don't know if this will help and this post is two months old. The camera store may be right that the synchronization is the issue which tends me to point a finger at the external flash. There are at least three different flash units that will flash when the picture is made but only one type will sync with the camera. A digital flash unit is different from a film flash so a Canon EX type is required to sync with Canon TTL or TTL II digital cameras. An EZ will flash but it's off a bit, so I can only assume that your Promaster and Canon flash units are for film cameras. Okay and another thing that could be throwing things off a bit is the camera may have been programed in Custom Functions to use "Second Curtain" or "Rear Curtain". Just seams to me if the built in flash works then it's the external units at fault.

the person suggests using a fingernail. (s)he must have long fingernails. I had to use a piece of paper folded in half. Swipe the paper from back to front, as in, from the eyepiece side towards the lens side.

Hi Chrissy, I had observed the same problem - after an external flash had been removed from the camera, internal flash didn't pop up. Tried to look at the Google and finally found the solution. It helped me and could help you as well:
The usual reason is that the camera thinks that there's an external flash mounted on the hot shoe. Check the external flash detect switch. It's located under the right side of the shoe (there is a metalic piece which is kind of "elastic". Just try to push it and release several times, may be put the screwdriver softly under it and out... It helped me. Here is the picture of location of the detector.

Remote Firing of Flash Units


The EOS 40D does not have a transmitter built in. The remote flash units must be set to "Slave" and the on-camera external flash unit (eg Speedlite 580EX) or transmitter (ST-E2) set to "Master". Note that the Speedlite 430EX doesn't have the function to act as Master and you need a minimum or the 580EX or a ST-E2 speedlite transmitter (or similar) as Master/s.

Exposure problem


Your 40D requires that you use an ETTL-II type flash like the Canon 380-EX. What flash are you using?
